TPS389018DSER TI Supervisory Circuit | 6-WSON (1.5x1.5) | 0.5% Threshold Accuracy, 1.8V Fixed

Product Overview

The TPS389018DSER from Texas Instruments is a high-accuracy supervisory circuit designed for monitoring power supply voltages in a variety of systems. It features a fixed threshold voltage of 1.8V with a precision of 0.5%, ensuring reliable reset generation during power-up, power-down, and brown-out conditions. Housed in a compact 6-WSON (1.5x1.5) package, it is ideal for space-constrained applications. The device offers a low quiescent current of 5.5 µA (typical) and supports a wide operating voltage range from 1.6V to 6.5V. It provides an active-low, open-drain RESET output with a built-in pull-up resistor, simplifying system integration.
